What's wrong with this motor? Help needed....
This is a Dayton split phase motor, 1/3hp
Motor will not start, no burned smell, shaft turns freely, age is 3.5 years, will not run after bypassing switch, No hum with power on. Resistance readings: 1.2, .3, .3

Very basic motor. No start cap. Just a centrifugal switch.
Remove red and black wires.
Check between the red and black wires for resistance. (start winding)
Check between the binding post for resistance. (run winding)
If either winding was open or the centrifugal switch was bad... you'd get a hum when connecting the motor. My guess a power to the motor issue.

The ratio 2.8 for start and 1.8 for run looks about right.
You'd need to use the lowest ohm setting available.
Since both windings are showing continuity..... you will need to check your application for 120vac. It sounds like you are not getting any voltage to the motor.

It wasn't at the motor connection, it was the power cord, wire broken almost totally into. I should have measured voltage at the terminals! Thanks everyone...
